Hi Indranil, These measurements are not fully correct, for example select count(*) might use only index and in select * was not actually invoked, because you need to run over cursor. Also by default query is not parallelized on one node, and scan with grouping is going sequentially in one thread.
Try to recheck your results on one node with enabled query parallelism: CacheConfiguration.setQueryParallelism(8) [1]. And/or on 4 server nodes with 1 backup. You should get better numbers because of spreading query over machines.
